KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de SAFETY REQUIREMENTS All user’s manual requirements as well as the provisions of all the applicable local and national construction, electrical, and technical norms and standards must be observed when installing and operating the unit. Disconnect the unit from the power supply prior to any connection, servicing, maintenance, and repair operations.
www.blaubergventilatoren.de KOMFOrt (EC) d5(B)180(-E) This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de PURPOSE The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream of intake air. The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with high humidity.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de TECHNICAL DATA The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de DESIGN AND OPERATING LOGIC The unit has the following operating logic: warm stale extract air from the room flows into the unit, where it is filtered by the extract filter, then air flows through the heat exchanger and is exhausted outside by the extract fan. Cold fresh air from the outside flows into the unit, where it is cleaned by the supply filter. Then the air flows through the heat exchanger and is directed to the room with the supply fan.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de UNIT OPERATION MODES Heat recovery Warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the heat exchanger and is exhausted outside with the extract fan. Cold fresh air from outside flows into the unit, where it is cleaned in the supply filter. Then the air flows through the heat exchanger and is directed to the room with the supply fan.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de MOUNTING AND SET-UP READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT. FS2 HUMIDITY SENSOR INSTALLATION AND CONNECTION The FS2 humidity sensor is not included in the delivery and can be ordered separately. Install the humidity sensor into the mount on the inner side of the unit and connect the humidity sensor to the appropriate connector.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de UNIT MOUNTING To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect the straight air duct section to the spigots on both sides of the unit while mounting. Minimum straight air duct length: • equal to 1 air duct diameter on intake side • equal to 3 air duct diameters on outlet side The air ducts must be slipped over the unit flanges until tight.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de While choosing fasteners consider the material of the mounting surface as well as the weigh of the unit, refer to the Technical Data section. Fasteners for unit mounting should be selected by the Customer Service technician. Unscrew the thumbscrews on the unit before attaching it to the mounting brackets. Set the unit thumbscrews into the mating cutouts in the mounting brackets and tighten the thumbscrews.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de Installation options according to diagrams 3-4 are possible for the KOMFORT (EC) D5(B)180-E modification. Exhaust Supply Intake Extract drain pipe Diagram 3. Wall vertical installation Extract Intake Supply Exhaust 302 Diagram 4.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de CONDENSATE DRAINAGE The KOMFORT (EC) D5(B)180 heat recovery units require condensate drainage. The hole for the drain pipes is in the cover of the unit. CAUTION! The drain pipe on the side of the intake air from the street is designed to drain condensate, which forms when the intake air is cooled in the heat exchanger if the unit is operating in a warm, humid climate.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de Then connect the drain pipe to the sewage system using the Siphon-Kit SFK 20x32 (available upon separate order). The pipes are required to have a minimum slope of 3°. Each drain pipe is connected to a different U-trap.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de CONNECTION TO POWER MAINS POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL. ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY. The air-handling unit is rated for connection to single-phase AC 220-240 V/50 (60) Hz power mains.

KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS. FOLLOW THE SAFETY REGULATIONS WHEN CARRYING OUT MAINTENANCE. Maintenance operations of the unit are required 3-4 times per year. They include general cleaning of the unit and the following operations: 1. Filter maintenance. Clogged filters increase air resistance in the system and reduce supply air volume.
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de 3. Fan maintenance (once per year). Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply air flow. Clean the fans with a soft cloth, brush, or using compressed air. Do not use water, aggressive solvents or sharp objects as they may damage the impeller. 4. Supply air flow control (twice per year).
KOMFOrt (EC) d5(B)180(-E) www.blaubergventilatoren.de STORAGE AND TRANSPORTATION REGULATIONS • • • • • • • Store the unit in the manufacturer’s original packaging box in a dry closed ventilated premise with temperature range from +5 ˚C up to +40 ˚C and relative humidity up to 70 %. Storage environment must not contain aggressive vapors and chemical mixtures provoking corrosion, insulation, and sealing deformation.
